* Pelobius tardus and Dytiscus circumcincttis did not occur at any of the stations 
considered in this table, but the name is inserted so that the list may contain the names of all 
species taken in the Broads District in 1904. Ccelambus decoratus, Gyll. almost certainly occurred 
in one or more of the districts, but was passed over as Hydroporus pictus F. , by mistake.
